FIELD OF TECHNOLOGY

The present invention relates to the field of sleep improvementtechnology, including, but not limited to the use of such technology inthe hospitality industry. Specifically, the invention relates to a sleepsystem including a set of textile products that, based on theircomposition, construction, and relative positioning with one other, canimprove the quality and comfort of the sleep environment, including overan extended period of time. The invention further relates to a sleepsystem that can be incorporated with existing mattresses and/ordecorative bedding. Additionally, the invention includes methods ofimproving the sleep environment using the inventive sleep system.

BACKGROUND

Scientists have observed that many critical functions take place duringsleep. During deep sleep, the body repairs muscles and tissues as wellas cellular damage, releases growth hormones, reduces blood pressure andthus cardiovascular work, boosts the immune system, and replenishesenergy reserves. During REM sleep, the brain processes, stores, andorganizes information, assisting in memory and learning. Long periods ofsleep are needed to obtain sufficient deep sleep and REM sleep tomaintain such functions.

Significant research has been undertaken to identify which conditionsare necessary to both fall asleep and remain asleep. The conditionsassociated with the “sleep chamber” in particular have been studied atlength. The “sleep chamber” is the space formed between the sheet thatis placed on top of the mattress/mattress topper (hereinafter a “fittedsheet”) and the flat sheet that covers a person when they are lying inbed. Both the layers of bedding below and above the sleep chamber affectthe conditions within the chamber and impact the quality and comfort ofsleep. While a person is at rest, the heat and water vapor emitted fromthe human body significantly increase the temperature and relativehumidity of the sleep chamber over time.

Ideally, conditions in the sleep chamber would keep the temperature ator below human body temperature and maintain a relative humidity of 65%or less throughout the sleep period. Unfortunately, most bedding doesnot allow for air breathability and permeability and fails to absorbwater vapor adequately. Over time, this creates a sleep chamber that ishot, humid, and not conducive to restful sleep.

To solve the heat and humidity issues of the sleep chamber, many suggestusing a new mattress that contains cooling materials and componentsand/or is made using construction methods that assist with air flow.Replacing a mattress, however, is a significant expense and createsmattress-related environmental waste, some of which may be toxic,particularly for memory foams. For hotels and other hospitalitylocations, mattress replacement may not be suitable for these reasons aswell as other reasons. In particular, most hotels have an eight to tenyear replacement cycle for mattresses—since the quality, composition,and functionality of the mattresses can vary greatly with age, it may bedifficult to determine which mattresses should be replaced.Additionally, in the hospitality industry, it is common to use mattressencasements that completely cover the mattress with near air-tightmaterials that encumber any air-flow and cooling technology that themattress may have been designed to create. These encasements eliminateany moisture absorption which is a critical component of maintaining anoptimal sleep environment within the sleep chamber.

There is a need for a sleep system that improves the comfort and qualityof the sleep environment by maintaining optimal temperature and humidityconditions inside the sleep chamber. There further is a need for a sleepsystem that does not require the replacement of the mattress to reachthe goal temperature and humidity conditions inside the sleep chamber.There also is a need for a sleep system that provides a consistent levelof comfort and quality of the sleep environment regardless of theunderlying mattress.
